Patented-Nov. co. iota Application filed September 19, 1914. Serial No.state].

To all whom it may concern:

Be it known that I, AMBROSE RIDD, Sl1bject of the King of Great Britain,resldmg at New Plymouth, in the Dominion of New Zealand, have invented anew and useful Improvement in Milking-Machine Releasers; and I do herebydeclare the following to be a full, clear, and exact description of thesame.

This invention relates to the appliances used in milking machineinstallations for the purpose of automatically releasing the milk fromthe main milk flow pipe used for the conveyance of the milk from theseveral cows. This milk is drawn along such pipe under the action ofsuction produced by connection with a source of vacuum and the presentreleaser in its operation is designed to receive the milk from such pipeand to deliver it into suitable receptacles without interfering with thecontinuity of such vacuum action and the consequent flow of the milk.

The means devised for carrying out this purpose relate to that classconsisting broadly of a two chambered vessel, one chamber being placedabove the other and being interposed into the milk and vacuum pipe lineso that it will receive the milk constantly. An outlet is provided inthe bottom of this receiving chamber and which outlet is kept normallyclosed by a gravity flap valve adapted to open outward. The lowerchamber fits over the bottom of the receiving chamber and it also isprovided with an outlet in its bottom kept normally closed by a ravityflap valve adapted to open outward. in automatic pulsator of any of thewell known constructions is connected with the vacuum main and with thelower chamber, so that such pulsator shall in its operation connect thelower chamber alternately with the vacuum pipe and with air. When thischamber is connected with vacuum the air conditions of both chambers arein equilibrium so that any milk contained in the upper chamber will byits weight force the discharge valve open and flow into the lowerchamber the discharge valve of such lower chamber being kept closed bythe air pressure outside. Then when air is admitted to the lower chamberthe air conditions in the two chambers will be varied so that the airpressure in the lower chamber and the vacuum in the upper chamber wlllclose the disence will be made to the accompanying sheet of drawings, inwhich Figure l is a part side elevation and part sect onal elevation ofthe complete releaser. F1g. 2 1s a front elevation of the same.

A is the receiving chamber which is made preferably of cylindrical formhaving a permanently closed top end and an open bottom end. This bottomend is however provided with a cover B fitting closely on to it andadapted to make an airtight connec-' tion. The cover is formed with awell or depression C in it and with a discharge opening D openinghorizontally from such depression. This opening is covered by the flapvalve hung upon its outside so that 1t may swmg out and in but which isso hung as to normally close the opening by its own weight.

F is the lower chamber the top of which is left open and which isadapted to fit 'closely around the edge of the cover B in the mannershown in the drawings. The cover B and thls chamber are then keptinposit1on upon the chamber A by means of the bow clamp G passing beneaththe center of the chamber F and engaging at its two ends with the collaror ring H upon the outside of the chamber A, and the clamping screw Jthat is threaded through the bow and en gages the chamber F and therebydraws the joints between the cover and the two chambers closelytogether. Rubber packing is preferably placed between these joints.

The lower chamber F is formed with the horizontal discharge outlet Kthat is controlled by means of the flap valve M hung upon its outsideface and which also is so hun as to normally close the outlet.

T e milk pipe N is arranged to enter the chamber A near its bottom whilethe vacuum pipe N' is led away from the top of such chamber.

() is a p'ulsator appliance of any of the well known constructions usedin milking. machinery and of the class that are auto-. maticallyoperated by being connected with v source of vacuum.

means of rubber hosing or otherfiexible' piping R so as thereby to causesuch chamber to be alternately exhausted of air and filled with it tooperate the appliance in the manner before described,

It will be seen that the several parts composing the releaser may bereadily taken apart for cleansing purposes by merely loosening the screwJ and removing the bow clamp G. When cleansed they may then be readilyre-assembled in their workin positions.

hat I doclaim as my invention, and desire to secure by Letters Patent isA milking machine releaser comprising an upperxmilk receiving chamberconnected.

chambers together consisting of a bow clamp extending beneath the'lowerchamber, having inwardly extending lugs on its two ends, a ring fixedaround the upper chamber over which said lugs extend, and a set screwpassing u through the middle of the bow clamp an engaging the bottom ofthe lower chamber, substantiallv as specified.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.

AMBROSE RIDD.
